I'm afraid I'm too stupid to see the most obvious solution and so I'm 
confusing everyone...

the pipeline above is in principle what I want. The problem is: I want 
to listen to a 'source' on the Win PA server! The data is available as 
something like a virtual line input. Normally one would use rtp-send to 
forward this stream as described in the documentation but the rtp 
modules are not available on windows. And since I'm not very familiar 
with windows I have to be happy with what I have on the windows side. 
I'm able to tunnel my Win PA source stream to the Lin PA. As expected 
I'm getting a new source inside my Lin PA. And when I start a vumeter 
for this source stream I can see the music I would like to hear. What to 
do then, how to send the stream data from a source to a sink? Maybe 
something like:

PA source -> socket -> netcat -> socket -> PA sink      via  the simple 
protocol
or
PA source -> gstreamer -> PA sink

or any other idea?
